Waifu Dominion

The pitch is right there in the tagline: a soy loser claws his way up to shadow god status by claiming waifus and prying loose their secrets. It's a rise-from-nothing power fantasy with a corruption angle bolted on, not shy about either half of that equation.

The setup implies a starting point of nothing and a climb toward ruling something called the Abyss, with women along the way who aren't simply won but worked on and turned. That's the whole arc as far as the source states it, and it's stated with a straight face.

Played day to day, this is about approaching, teasing, and slowly corrupting a roster of women until loyalty (or something like it) flips your way, mixed with voyeurism and exhibitionism beats and the occasional partner who isn't quite yours. It runs as a mobile-friendly visual novel loop rather than a stat-heavy sim, so expect reading and choosing over managing spreadsheets.
